The main objectives and tasks of the three-year reform of state-owned enterprises have been completed. This is the key focus of the recent videoconference on the summary of the three-year action of the national state-owned enterprise reform. This achievement is closely related to the efforts of all parties in the past three years. Among them, scientific and technological innovation plays a very important role. The meeting pointed out that in the past three years, "the system and mechanism to encourage scientific and technological innovation have been constantly improved". Stimulating the scientific and technological innovation vitality of state-owned enterprises is a key measure to achieve China's high-level scientific and technological self-reliance, and also an important way to deepen the reform of state-owned enterprises and improve the core competitiveness of state-owned enterprises. The enterprise is the micro implementation subject. Especially for state-owned enterprises, they play a leading role in major scientific and technological innovation. Through unremitting exploration and optimization of top-level system design, China has launched a series of science and technology policies to support and promote the independent innovation of state-owned enterprises. In the past three years, state-owned enterprises have made significant achievements in scientific and technological innovation in many aspects by virtue of their innovative strength and advantages, and have become the main force of scientific and technological innovation in China. However, at present, state-owned enterprises, especially central enterprises, urgently need to further promote the deep integration of industrial chain and innovation chain by giving full play to the advantages of industrial chain length mechanism, and establish and improve the collaborative innovation pattern of state-owned enterprises and private enterprises. Actively assuming the function of industrial chain leader is an important way for state-owned enterprises to promote the deep integration of industrial chain and innovation chain, enhance the innovation-driven ability, and improve the transformation of scientific and technological innovation achievements. The deep integration and development of industrial chain and innovation chain can promote demand-oriented scientific and technological innovation, reduce the "island" phenomenon existing in existing scientific and technological innovation activities to a certain extent, and stimulate the motivation and willingness of state-owned enterprises in scientific and technological innovation. The establishment and improvement of the cooperative innovation pattern between state-owned enterprises and private enterprises is an important embodiment of the market-oriented mechanism operation of state-owned enterprises, and also an important channel for enterprises of different ownership to complement each other. State-owned enterprises can help private enterprises alleviate the financial pressure and institutional obstacles, stimulate the willingness of private enterprises to innovate in science and technology, and create a good market environment by giving full play to the advantages of chain length integration and state-owned equity participation. By means of mixed ownership reform and market-oriented cooperation, private enterprises can participate in the internal governance and external supervision of state-owned enterprises, reduce the corporate governance obstacles that may exist in the scientific and technological innovation of state-owned enterprises, thus forming a good situation of mutual integration and joint development of state-owned and private economies, and providing strong support for state-owned enterprises to improve the vitality of scientific and technological innovation. In the process of stimulating the vitality of scientific and technological innovation, state-owned enterprises should strengthen the strategic and goal orientation, and build a modern scientific and technological innovation system around emerging industries such as digital technology. Focusing on the short board of the industrial chain, we should strengthen basic research, improve the market-oriented allocation of innovation factors among regions, mobilize the enthusiasm of state-owned enterprises for scientific and technological innovation, and reduce the possible market barriers to scientific and technological innovation of state-owned enterprises. In the process of promoting the collaborative innovation of state-owned enterprises and private enterprises, local governments should strengthen the guiding role of government funds, increase support for private capital, and improve the institutional design of state-owned capital participating in private enterprise governance according to local actual conditions. We should give full play to the resource effect of the state-owned economy for private enterprises and strengthen the integration of the state-owned economy and private economy
